I understand that broadcasting arrays are strictly controlled so I wondered if an array that could radiate in pre designated areas would be useful as it would not require a reflector to repell radiation. ___________ Examples in use for many decades already are the directional arrays used in AM broadcasting, where all elements (towers) in the array are driven. The element spacings & orientations, and the relative power & phase applied to each element determine the net radiation pattern of the array. RF Thanks ART |
